S. S. <i>Leviathan</i> Engine Order Telegraph

1923

This telegraph was used to communicate speed and direction orders from the wheelhouse of the ocean liner <i>Leviathan</i> to one of its engine rooms. Most modern ships have a throttle, but for steamers it was necessary for the pilot to contact the engine room with instructions for the engineer that were relayed to the boilermen. This telegraph would signal full, half, slow, dead slow, finished with engine, and stop—both astern and ahead.
